Abstract: A real time multiplexed bit allocation in a 8 kbps frame unit of a transmission frame having a repeating cycle of 8khz is realised in a variable fashion such that an automatic matching of a transmission frame is achieved at an initiation of a transmission and that error check bits of the error correction code are contained in a transmission frame with a satisfactory matching. In addition, the multiframe configuration enables it to handle in an integrated fashion the synchronizations of the voice data frame, the error correction frame, and the video data packet, which as a result minimizes the size of the buffer memories disposed to send and/or to receive moving pictures and which enables the transmission speed smoothing operation to be accomplished in a simple configuration through an easy control.

Abstract: A valve (30) in a medical ventilator (10) opens and closes as is needed to permit venting of respiratory gasses from a patient (14) to the atmosphere. Changes in position of the valve (30) are caused by a stepper motor (48), which is joined to the valve by a mechanical linkage. The stepper motor (48), in turn, is powered by electronic signals from a microcomputer controller (26). The position of the valve is controlled on a closed loop basis by the controller (26), which receives feedback regarding the pressure of the proximal gases from a pressure transducer (34). The valve (30) is uniquely designed to enable the controller (26) to cause the valve to open quickly once the patient (14) begins to exhale, and to permit accurate control over the proximal pressure as the valve (30), is approaching the closed position. In particular, the valve (30) comprises a poppet (42) and a valve seat (44) which have curved mating surfaces (108, 110), with the curved surface (110) on the poppet (42) being truncated so that pressure gain variance is minimized over the range of positions of the poppet (42) relative to the valve seat (44). To enhance this improved pressure gain characteristic, a cam (52) in the linkage between the poppet (42) and stepper motor (48) has a variable pitch. All of the components of the valve which are exposed to respiratory gases are easily removed for sterilization and replacement. Further, the poppet (42) is movable to ensure complete closure of the valve despite variability in the tolerances of the replacement components.

Abstract: A telephone circuit, which may be monolithically integrated, for supplying ringing signals to a subscriber telephone line and for detecting unhooking during ringing comprises a logic control circuit (C) connected to exchange components which control the supply of the ringing signals and determine their rhythm. The logic circuit (C) is connected to a circuit means (RS) for detecting direct current on the line and a current comparator (COMP) for generating a signal when the value of the line current exceeds a predetermined current value. This signal is also supplied to the exchange components via a transfer circuit (HS) to inform them that unhooking has taken place. The logic control circuit is connected to a timing signal generator (FC) which synchronizes its functions with instants in which the ringing signal has a zero amplitude, to a signal amplifier circuit (SA)   which supplies the ringing signals to the line and to the transfer circuit (HS). When the direct current detecting circuit means (RS) signals a probable unhooking, the logic control circuit (C) disables the amplifier circuit (SA) from supplying ringing signals to the line and inhibits the transfer of any signals to the exchange components, checking after a predetermined time interval that unhooking has actually taken place.

Abstract: A musical tone control apparatus having first and second detecting means (30R, 30H) mounted on a player's arm for detecting bending angles of player's joints, a musical tone control data generating means (29) worn on the player's waist for generating musical tone control data based on output signals of the first and second detecting means (30R, 30H). The musical tone control data generating means (29) is connected to the first detecting means (30R) via the second detecting means (30H) through a single common cable (i.e. transmitting means). Hence, the number of common cables (i.e. the number of transmitting means) can be reduced to the minimum, allowing free movement of the player. Further, the first detecting means (30R) having a potentiometer comprises first and second links rotatably connected at their ends so that the links rotate in a bending direction of the player's joint, a resistance element provided at the first link, and a sliding contact provided at the second link. The sliding contact, keeping contact with the resistance element, slides thereon with the rotation of the first or second link. The potentiometer produces a signal between the sliding contact and the terminal of the resistance element in response to a bending angle of the player's joint. Hence, the detecting means can be made thin, allowing free motion of the player's arm.

Abstract: An improved arrangement for digital signal encryption using a cipher algorithm in which a multi-bit key signal (K) is used to produce a first keystream signal (Ks1) of coding bytes which are used in an exclusive-OR logical operation with data bytes of a received digital data signal (Cds) to produce an enciphered/deciphered output digital data signal (DS). Hitherto, the keystream signal was also fed back into the algorithm for processing with the key signal, but this was found to result in an insecure arrangement because the keystream signal can be found by exclusive-ORing the received digital data signal with only a few bytes of the output data signal that are already known, following which the key signal itself can be deduced by a fairly simple trial-and-error computing procedure. The improvement consists in feeding back into the algorithm a keystream signal (Ks2) which is not the same as that used for the exclusive-OR logical operation. This different keystream signal (Ks2) can be produced either directly or indirectly from the keystream signal (Ks1) used for the exclusive-OR logical operation. Figures 3 and 7 show these two possible ways of producing the different keystream signal.

Abstract: An improved operational transconductance amplifier (OTA) for use in sample-and-hold circuits or the like requiring very low output leakage currents and equalized output current transients when the OTA is placed in stand-by (disabled.) The OTA has an output stage that is referenced to ground by having two darlington pairs with common collector outputs as the output for the OTA in a common base configuration such that when the OTA is disabled, any leakage paths from the output of the OTA are coupled to ground. Further, the OTA is compensated internally to equalize any current transient output when the OTA is placed in stand-by such that the integral of the current transient out of the OTA is substantially the same as the integral of the current transient into the OTA from the integrator. A sample-and-hold circuit is also described utilizing the improved OTA.

Abstract: A pyramid polygon scanner (12) wherein the differential scan length between multiple beams can be eliminated by tilting the beams (5, 5A) with respect to the photoreceptor surface (50). Thus the beam (59) with the shorter scan length when the beams are normal to the photoreceptor, travel a greater distance before impinging on the photoreceptor. At the start or end of scan the scan angle is not zero, so the scan lengths for the beams with the larger travel distances are increased by the extra distance multiplied by the tangent of the scan angle. At the proper tilt angle, all scan lengths at the photoreceptor are the same. Since the angular scan rate of all the beams are always the same, over the entire scan, the scan lengths of the individual beams will always be the same, at any fraction of the total scan. Thus the information written onto the photoreceptor by the multiple beams will be in alignment for all simultaneous beams.
